the case of the initial Loans to be made on the Closing Date, and [Section]12,
in the case of all other Loans, have been satisfied on the date of such request.

2.2. COMMITMENT FEE. The Borrower agrees to pay to the Agent for the
accounts of the Banks in accordance with their respective Commitment Percentages
a commitment fee calculated at a rate per annum equal to the Applicable
Commitment Fee Percentage on the average daily amount during each calendar
quarter or portion thereof from Closing Date to the Revolving Credit Loan

[Section]9.1(k)(i) and up to a maximum of $100,000,000 in connection with any

shall not be reduced below $50,000,000 unless it is terminated in full; and
PROVIDED FURTHER that if, within one (1) year following the Closing Date, the
Borrower incurs Indebtedness permitted by [Section]9.1(k) or sells equity
securities of the Borrower, or warrants or subscription rights for equity
securities of the Borrower, the sale or issuance of any of which does not create
or result in a Default or Event of Default, in an aggregate amount for all such
Indebtedness

-16-

and net proceeds of the sale of such equity securities, or warrants
or subscription rights for equity securities, in excess of $75,000,000, and the
Borrower, at its option, reduces the Total Commitment by more than $75,000,000,
the Borrower shall, at the time of such reduction of the Total Commitment, pay
to the Agent, for the PRO RATA benefit of the Banks, a fee equal to one fifth of
one percent (.20%) on the amount by which such reduction in the Total Commitment
exceeds $75,000,000. Upon any such reduction of the Total Commitment as set
forth in either of the two immediately preceding sentences, the Commitments of
the Banks shall be reduced PRO RATA in accordance with their respective
Commitment Percentages of the amount specified in such notice or, as the case
may be, terminated. Promptly after receiving any notice of the Borrower
delivered pursuant to this [Section]2.3.2, the Agent will notify the Banks of
the substance thereof. Upon the effective date of any such reduction or
termination, the Borrower shall pay to the Agent for the respective accounts of
the Banks the full amount of any commitment fee then accrued on the amount of

Bank's Commitment or, if less, the outstanding amount of all Loans made by such
Bank, plus interest accrued thereon, as set forth below. The Borrower
irrevocably authorizes each Bank to make or cause to be made, at or about the
time of the Drawdown Date of any Loan or at the time of receipt of any payment
of principal on such Bank's Note, an appropriate computer entry or other record
reflecting the making of such Loan or (as the case may be) the receipt of such
payment. The outstanding amount of the Loans set forth in such computer entries
or other records shall be PRIMA FACIE evidence of the principal amount thereof
owing and unpaid to such Bank, but the failure to record, or any error in so
recording, any such amount in such computer entries or other records shall not
limit or otherwise affect the obligations of the Borrower hereunder or under any
Note to make payments of principal of or interest on any Note when due.

2.5. INTEREST ON LOANS. Except as otherwise provided in [Section]5.10,

notice in the form of EXHIBIT B hereto (or telephonic notice confirmed in a

Credit Loan and (D) the Type of such Loan. Promptly upon receipt of any such
notice, the Agent shall notify each of the Banks thereof. Each Loan Request

to accept the Loan requested from the Banks on the proposed Drawdown Date. Each
Loan Request shall be in a minimum aggregate amount of $5,000,000 or an integral
multiple thereof.

2.7. CONVERSION OPTIONS.
------------------

2.7.1. CONVERSION TO DIFFERENT TYPE OF LOAN. The Borrower may elect
from time to time to convert any outstanding Loan to a Loan of another
Type, PROVIDED that (i) with respect to any such conversion of a Loan to a
Base Rate Loan, the Borrower shall give the Agent at least one (1) Business
Day prior written notice of such election; (ii) with respect to any such
conversion of a Base Rate Loan to a Eurodollar Rate Loan, the Borrower
shall give the Agent at least three (3) Eurodollar Business Days prior
written notice of such election; (iii) with respect to any such conversion
of a Eurodollar Rate Loan into a Loan of another Type, such conversion
shall only be made on the last day of the Interest Period with respect
thereto; and (iv) no Loan may be converted into a Eurodollar Rate Loan when
any Default or Event of Default has occurred and is continuing. On the date
on which such conversion is being made, each Bank shall take such action as
is necessary to transfer its Commitment Percentage of such Loans to its
Domestic Lending Office or its Eurodollar Lending Office, as the case may
be. All or any part of outstanding Loans of any Type may be converted into
a Loan of another Type as provided herein, PROVIDED that any partial
conversion shall be in an aggregate principal amount of $5,000,000 or a
whole multiple thereof. Each Conversion Request relating to the conversion
of a Loan to a Eurodollar Rate Loan shall be irrevocable by the Borrower.

2.7.2. CONTINUATION OF TYPE OF LOAN. Any Loan of any Type may be
continued as a Loan of the same Type upon the expiration of an Interest
Period with respect thereto by compliance by the Borrower with the notice
provisions contained in [Section]2.7.1; PROVIDED that no Eurodollar Rate
Loan may be continued as such when any Default or Event of Default has
occurred and is continuing, but shall be automatically converted to a Base
Rate Loan on the last day of the first Interest Period

-18-

relating thereto ending during the continuance of any Default or Event of
Default of which officers of the Agent active upon the Borrower's account
have actual knowledge. In the event that the Borrower fails to provide any
such notice with respect to the continuation of any Eurodollar Rate Loan as
such, then such Eurodollar Rate Loan shall be automatically converted to a
Base Rate Loan on the last day of the first Interest Period relating
thereto. The Agent shall notify the Banks promptly when any such automatic
conversion contemplated by this [Section]2.7 is scheduled to occur.

2.7.3. EURODOLLAR RATE LOANS. Any conversion to or from Eurodollar
Rate Loans shall be in such amounts and be made pursuant to such elections
so that, after giving effect thereto, the aggregate principal amount of all
Eurodollar Rate Loans having the same Interest Period shall not be less
than $20,000,000 or a whole multiple of $5,000,000 in excess thereof. At no
time shall there be more than five (5) Eurodollar Rate Loans outstanding.

the proposed Drawdown Date of any Loans, each of the Banks will make
available to the Agent, at its Head Office, in immediately available funds,

requested Loans. Upon receipt from each Bank of such amount, and upon
receipt of the documents required by [Section][Section]11 and 12 and the
satisfaction of the other conditions set forth therein, to the extent
applicable, the Agent will make available to the Borrower the aggregate
amount of such Loans made available to the Agent by the Banks. The failure
or refusal of any Bank to make available to the Agent at the aforesaid time
and place on any Drawdown Date the amount of its Commitment Percentage of
the requested Loans shall not relieve any other Bank from its several
obligation hereunder to make available to the Agent the amount of such
other Bank's Commitment Percentage of any requested Loans.

2.8.2. ADVANCES BY AGENT. The Agent may, unless notified to the
contrary by any Bank prior to a Drawdown Date, assume that such Bank has
made available to the Agent on such Drawdown Date the amount of such Bank's
Commitment Percentage of the Loans to be made on such Drawdown Date, and
the Agent may (but it shall not be required to), in reliance upon such
assumption, make available to the Borrower a corresponding amount. If any
Bank makes available to the Agent such amount on a date after such Drawdown
Date, such Bank shall pay to the Agent on demand an amount equal to the
product of (i) the average computed for the period referred to in clause
(iii) below, of the weighted average interest rate paid by the Agent for
federal funds acquired by the Agent during each day included in such
period, TIMES (ii) the amount of such Bank's Commitment Percentage of such
Loans, TIMES (iii) a fraction, the numerator of which is the number of days
that elapse from and

-19-

including such Drawdown Date to the date on which the amount of such Bank's
Commitment Percentage of such Loans shall become immediately available to
the Agent, and the denominator of which is 360. A statement of the Agent
submitted to such Bank with respect to any amounts owing under this
paragraph shall be PRIMA FACIE evidence of the amount due and owing to the
Agent by such Bank. If the amount of such Bank's Commitment Percentage of
such Loans is not made available to the Agent by such Bank within three (3)
Business Days following such Drawdown Date, the Agent shall be entitled to
recover such amount from the Borrower on demand, with interest thereon at
the rate per annum applicable to the Loans made on such Drawdown Date.

3. REPAYMENT OF THE REVOLVING CREDIT LOANS.
---------------------------------------

3.1. MATURITY. The Borrower promises to pay on the Revolving Credit Loan
Maturity Date, and there shall become absolutely due and payable on the
Revolving Credit Loan Maturity Date, all of the Loans outstanding on such date,
together with any and all accrued and unpaid interest thereon.

3.2. MANDATORY REPAYMENTS OF LOANS. If at any time the Borrower shall incur
Indebtedness permitted by [Section]9.1(k), the Borrower shall, at the request of
the Majority Banks, immediately pay to the Agent for the respective accounts of
the Banks an amount equal to the net proceeds of all such Indebtedness incurred
following the Closing Date, up to a maximum of $50,000,000 in connection with
any such Indebtedness described in [Section]9.1(k)(i) and up to a maximum of
$100,000,000 in connection with any such Indebtedness described in
[Section]9.1(k)(ii). If at any time the sum of the outstanding amount of the
Loans, the Maximum Drawing Amount and all Unpaid Reimbursement Obligations
exceeds the Total Commitment, then the Borrower shall immediately pay the amount
of such excess to the Agent for the respective accounts of the Banks. Any
amounts repaid in accordance with either of the immediately preceding two
sentences shall be applied: first, to any Unpaid Reimbursement Obligations;
second, to the Loans; and third, to provide to the Agent cash collateral for
Reimbursement Obligations as contemplated by [Section]4.2(b) and (c). Each
payment of any Unpaid Reimbursement Obligations or prepayment of Loans shall be
allocated among the Banks, in proportion, as nearly as practicable, to each
Reimbursement Obligation or (as the case may be) the respective unpaid principal
amount of each Bank's Note, with adjustments to the extent practicable to
equalize any prior payments or repayments not exactly in proportion.

3.3. OPTIONAL REPAYMENTS OF LOANS. The Borrower shall have the right, at
its election, to repay the outstanding amount of the Loans, as a whole or in
part, at any time without penalty or premium, PROVIDED that any full or partial
prepayment of the outstanding amount of any Eurodollar Rate Loans pursuant to
this [Section]3.3 may be made only on the last day of the Interest Period
relating thereto. The Borrower shall give the Agent, no later than 10:00 a.m.,
Boston time, at least one (1) Business Day prior written notice of any proposed
prepayment pursuant to this [Section]3.3 of Base Rate Loans, and three (3)
Eurodollar

-20-

Business Days notice of any proposed prepayment pursuant to this [Section]3.3 of
Eurodollar Rate Loans, in each case specifying the proposed date of prepayment
of Loans and the principal amount to be prepaid. Each such partial prepayment of
the Loans shall be in an integral multiple of $5,000,000 and shall be applied,
in the absence of instruction by the Borrower, first to the principal of Base
Rate Loans and then to the principal of Eurodollar Rate Loans. Accrued interest
on the principal prepaid in connection with each such partial prepayment shall
be due and payable on the next Interest Payment Date, but accrued interest on
the principal paid in connection with any full prepayment at a time when the
Total Commitment is terminated shall be paid on the date of prepayment. Each
prepayment shall be allocated among the Banks, in proportion, as nearly as
practicable, to the respective unpaid principal amount of each Bank's Note, with
adjustments to the extent practicable to equalize any prior repayments not
exactly in proportion.

4. LETTERS OF CREDIT.
-----------------

4.1. LETTER OF CREDIT COMMITMENTS.
----------------------------

4.1.1. COMMITMENT TO ISSUE LETTER OF CREDIT. Subject to the terms and
conditions hereof and the execution and delivery by the Borrower of a
letter of credit application on the Agent's customary form (a "Letter of
Credit Application"), the Agent on behalf of the Banks and in reliance upon
the agreement of the Banks set forth in [Section]4.1.4 and upon the
representations and warranties of the Borrower contained herein, agrees, in
its individual capacity, to issue, extend and renew for the account of the
Borrower one or more standby or documentary letters of credit
(individually, a "Letter of Credit"), in such form as may be requested from
time to time by the Borrower and agreed to by the Agent; PROVIDED, HOWEVER,
that, after giving effect to such request, (a) the sum of the aggregate
Maximum Drawing Amount and all Unpaid Reimbursement Obligations shall not
exceed $15,000,000 at any one time and (b) the sum of (i) the Maximum
Drawing Amount on all Letters of Credit, (ii) all Unpaid Reimbursement
Obligations, and (iii) the amount of all Loans outstanding (after giving
effect to all amounts requested) shall not exceed the Total Commitment.

4.1.2. LETTER OF CREDIT APPLICATIONS. Each Letter of Credit
Application shall be completed to the satisfaction of the Agent. In the
event that any provision of any Letter of Credit Application shall be
inconsistent with any provision of this Credit Agreement, then the
provisions of this Credit Agreement shall, to the extent of any such
inconsistency, govern.

4.1.3. TERMS OF LETTERS OF CREDIT. Each Letter of Credit issued,
extended or renewed hereunder shall, among other things, (i) provide for
the payment of sight drafts for honor thereunder when presented in
accordance with the terms thereof and when accompanied by the documents
described therein, (ii) have an expiry date (which may be

-21-

extended annually by the Agent, at its option upon the request of the
Borrower) no more than one year following its date of issue and (iii) have
an expiry date no later than the date which is fourteen (14) days (or, if
the Letter of Credit is confirmed by a confirmer or otherwise provides for
one or more nominated persons, forty-five (45) days) prior to the Revolving
Credit Loan Maturity Date. Each Letter of Credit so issued, extended or
renewed shall be subject to the Uniform Customs.

4.1.4. REIMBURSEMENT OBLIGATIONS OF BANKS. Each Bank severally agrees
that it shall be absolutely liable, without regard to the occurrence of any
Default or Event of Default or any other condition precedent whatsoever, to
the extent of such Bank's Commitment Percentage, to reimburse the Agent on
demand for the amount of each draft paid by the Agent under each Letter of
Credit to the extent that such amount is not reimbursed by the Borrower
pursuant to [Section]4.2 (such agreement for a Bank being called herein the
"Letter of Credit Participation" of such Bank).

4.1.5. PARTICIPATIONS OF BANKS. Each such payment made by a Bank shall
be treated as the purchase by such Bank of a participating interest in the
Borrower's Reimbursement Obligation under [Section]4.2 in an amount equal
to such payment. Each Bank shall share in accordance with its participating
interest in any interest which accrues pursuant to [Section]4.2.

4.2. REIMBURSEMENT OBLIGATION OF THE BORROWER. In order to induce the Agent
to issue, extend and renew each Letter of Credit and the Banks to participate
therein, the Borrower hereby agrees to reimburse or pay to the Agent, for the
account of the Agent or (as the case may be) the Banks, with respect to each
Letter of Credit issued, extended or renewed by the Agent hereunder,

(a) except as otherwise expressly provided in [Section]4.2(b) and (c),
on each date that any draft presented under such Letter of Credit is
honored by the Agent, or the Agent otherwise makes a payment with respect
thereto, (i) the amount paid by the Agent under or with respect to such
Letter of Credit, and (ii) the amount of any taxes, fees, charges or other
reasonable costs and expenses whatsoever incurred by the Agent or any Bank
in connection with any payment made by the Agent or any Bank under, or with
respect to, such Letter of Credit,

(b) upon the reduction (but not termination) of the Total Commitment
to an amount less than the Maximum Drawing Amount, an amount equal to such
difference, which amount shall be held by the Agent for the benefit of the
Banks and the Agent in an interest bearing account selected by the Agent as
cash collateral for all Reimbursement Obligations, and

-22-

(c) upon the termination of the Total Commitment, or the acceleration
of the Reimbursement Obligations with respect to all Letters of Credit in
accordance with [Section]13, an amount equal to the then Maximum Drawing
Amount on all Letters of Credit, which amount shall be held by the Agent
for the benefit of the Banks and the Agent in an interest bearing account
selected by the Agent as cash collateral for all Reimbursement Obligations.

Each such payment shall be made to the Agent at the Agent's Head Office in
immediately available funds. Interest on any and all amounts remaining unpaid by
the Borrower under this [Section]4.2 at any time from the date such amounts
become due and payable (whether as stated in this [Section]4.2, by acceleration
or otherwise) until payment in full (whether before or after judgment) shall be
payable to the Agent on demand at the rate specified in [Section]5.10 for
overdue principal on the Loans. So long as no Default or Event of Default has
occurred and is continuing, the Agent shall return amounts held as cash
collateral pursuant to [Section]4.2(b) or as a result of the Borrower's
termination of the Total Commitment pursuant to [Section]4.2(c) within a
reasonable time following the expiration or cancellation of any Letter of
Credit, with the amount being so returned equal to the Maximum Drawing Amount of
such expired or cancelled Letter of Credit.

4.3. LETTER OF CREDIT PAYMENTS. If any draft shall be presented or other
demand for payment shall be made under any Letter of Credit, the Agent shall
notify the Borrower of the date and amount of the draft presented or demand for
payment and of the date and time when it expects to pay such draft or honor such
demand for payment. If the Borrower fails to reimburse the Agent as provided in
[Section]4.2 on or before the date that such draft is paid or other payment is
made by the Agent, the Agent may at any time thereafter notify the Banks of the
amount of any such Unpaid Reimbursement Obligation. No later than 3:00 p.m.
(Boston time) on the Business Day next following the receipt of such notice,
each Bank shall make available to the Agent, at its Head Office, in immediately
available funds, such Bank's Commitment Percentage of such Unpaid Reimbursement
Obligation, together with an amount equal to the product of (i) the average,
computed for the period referred to in clause (iii) below, of the weighted
average interest rate paid by the Agent for federal funds acquired by the Agent
during each day included in such period, TIMES (ii) the amount equal to such
Bank's Commitment Percentage of such Unpaid Reimbursement Obligation, TIMES
(iii) a fraction, the numerator of which is the number of days that elapse from
and including the date the Agent paid the draft presented for honor or otherwise
made payment to the date on which such Bank's Commitment Percentage of such
Unpaid Reimbursement obligation shall become immediately available to the Agent,
and the denominator of which is 360. The responsibility of the Agent to the
Borrower and the Banks shall be only to determine that the documents (including
each draft) delivered under each Letter of Credit in connection with such
presentment shall be in conformity in all material respects with such Letter of
Credit, and upon such determination, the Agent shall honor a demand for payment
under such Letter of Credit.

-23-

4.4. OBLIGATIONS ABSOLUTE. The Borrower's obligations under this [Section]4
shall be absolute and unconditional under any and all circumstances and
irrespective, so long as the Agent has honored any appropriate demand for
payment with respect to any Letter of Credit, of the occurrence of any Default
or Event of Default or any condition precedent whatsoever or any setoff,
counterclaim or defense to payment which the Borrower may have or have had
against the Agent, any Bank or any beneficiary of a Letter of Credit. The
Borrower further agrees with the Agent and the Banks that the Agent and the
Banks shall not be responsible for, and the Borrower's Reimbursement Obligations
under [Section]4.2 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon, even if such documents
should in fact prove to be in any or all respects invalid, fraudulent or forged,
or any dispute between or among the Borrower, the beneficiary of any Letter of
Credit or any financing institution or other party to which any Letter of Credit
may be transferred or any claims or defenses whatsoever of the Borrower against
the beneficiary of any Letter of Credit or any such transferee. The Agent and
the Banks shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit. The Borrower agrees that
any action taken or omitted by the Agent or any Bank under or in connection with
each Letter of Credit and the related drafts and documents, if done in good
faith and with commercial reasonableness, shall be binding upon the Borrower and
shall not result in any liability on the part of the Agent or any Bank to the
Borrower.

4.5. RELIANCE BY ISSUER. To the extent not inconsistent with [Section]4.4,
the Agent shall be entitled to rely, and shall be fully protected in relying
upon, any Letter of Credit, draft, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel, independent accountants and
other experts selected by the Agent. The Agent shall be fully justified in
failing or refusing to take any action under this Agreement unless it shall
first have received such advice or concurrence of the Majority Banks as it
reasonably deems appropriate or it shall first be indemnified to its reasonable
satisfaction by the Banks against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement in accordance with a request of the Majority Banks,
and such request and any action taken or failure to act pursuant thereto shall
be binding upon the Banks and all future holders of the Notes or of a Letter of
Credit Participation.

4.6. LETTER OF CREDIT FEE. The Borrower shall, on the date of issuance or
any extension or renewal of any Letter of Credit and at such other time or times
as such charges are customarily made by the Agent, pay a fee (in each case, a
"Letter of Credit Fee") to the Agent (i) in respect of each standby Letter of
Credit equal to (A) the Applicable Eurodollar Rate Margin in effect on such date
MULTIPLIED BY the face amount of such standby Letter of Credit PLUS (B) the

-24-

Agent's customary issuance fee PLUS (C) a fronting fee (for the account of the
Agent) equal to one-eighth of one percent (0.125)% per annum of the face amount
of such standby Letter of Credit, and (ii) in respect of each documentary Letter
of Credit equal to (A) the Agent's customary administrative fees PLUS (B) the
Applicable Eurodollar Rate Margin in effect on such date MULTIPLIED BY the face
amount of such documentary Letter of Credit, PLUS (C) a fronting fee to the
Agent equal to one-eighth of one percent (0.125%) per annum of the face amount
of such documentary Letter of Credit, such Letter of Credit Fee (but not such
issuance, administrative or fronting fees) to be for the accounts of the Banks
in accordance with their respective Commitment Percentages.

5. CERTAIN GENERAL PROVISIONS.
--------------------------

5.1. FEES. The Borrower agrees to pay to the Agent the fees described in
the letter dated as of the date hereof between the Agent and the Borrower (the
"Agent's Side Letter") in accordance with the terms and conditions thereof.

5.2. FUNDS FOR PAYMENTS.
------------------

5.2.1. PAYMENTS TO AGENT. All payments of principal, interest,
Reimbursement Obligations, commitment fees, Letter of Credit Fees and any
other amounts due hereunder or under any of the other Loan Documents shall
be made to the Agent, for the respective accounts of the Banks and the
Agent, at the Agent's Head Office or at such other location in the Boston,
Massachusetts, area that the Agent may from time to time designate, in each
case in immediately available funds.

5.2.2. NO OFFSET, ETC. All payments by the Borrower hereunder and
under any of the other Loan Documents shall be made without setoff or
counterclaim and free and clear of and without deduction for any taxes,
levies, imposts, duties, charges, fees, deductions, withholdings,
compulsory loans, restrictions or conditions of any nature now or hereafter
imposed or levied by any jurisdiction or any political subdivision thereof
or taxing or other authority therein unless the Borrower is compelled by
law to make such deduction or withholding. If any such obligation is
imposed upon the Borrower with respect to any amount payable by it
hereunder or under any of the other Loan Documents, the Borrower will pay
to the Agent, for the account of the Banks or (as the case may be) the
Agent, on the date on which such amount is due and payable hereunder or
under such other Loan Document, such additional amount in Dollars as shall
be necessary to enable the Banks or the Agent to receive the same net
amount which the Banks or the Agent would have received on such due date
had no such obligation been imposed upon the Borrower. The Borrower will
deliver promptly to the Agent certificates or other valid vouchers for all
taxes or other charges deducted from or paid with respect to payments made
by the Borrower hereunder or under such other Loan Document.

32
-25-

5.3. COMPUTATIONS. All computations of interest on the Loans and of
commitment fees, Letter of Credit Fees or other fees shall, unless otherwise
expressly provided herein, be based on a 360-day year and paid for the actual
number of days elapsed; PROVIDED, HOWEVER, that computations of interest on Base
Rate Loans shall be based on a 365 or, as the case may be, 366-day year and paid
for the actual number of days elapsed. Except as otherwise provided in the
definition of the term "Interest Period" with respect to Eurodollar Rate Loans,
whenever a payment hereunder or under any of the other Loan Documents becomes
due on a day that is not a Business Day, the due date for such payment shall be
extended to the next succeeding Business Day, and interest shall accrue during
such extension. The outstanding amount of the Loans as reflected on the records
on each Bank and the Agent from time to time shall be considered correct and
binding on the Borrower unless within five (5) Business Days after receipt of
any notice from the Agent or any of the Banks of such outstanding amount, the
Borrower shall notify the Agent or such Bank to the contrary.

5.4. INABILITY TO DETERMINE EURODOLLAR RATE. In the event, prior to the
commencement of any Interest Period relating to any Eurodollar Rate Loan, the
Agent shall determine or be notified by the Majority Banks that adequate and
reasonable methods do not exist for ascertaining the Eurodollar Rate that would
otherwise determine the rate of interest to be applicable to any Eurodollar Rate
Loan during any Interest Period, the Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks. In such event (i) any Loan Request or
Conversion Request with respect to Eurodollar Rate Loans shall be automatically
withdrawn and shall be deemed a request for Base Rate Loans, (ii) each
Eurodollar Rate Loan will automatically, on the last day of the then current
Interest Period relating thereto, become a Base Rate Loan, and (iii) the
obligations of the Banks to make Eurodollar Rate Loans shall be suspended until
the Agent determines that the circumstances giving rise to such suspension no
longer exist, whereupon the Agent shall so notify the Borrower and the Banks.

5.5. ILLEGALITY. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or in the interpretation
or application thereof shall make it unlawful for any Bank to make or maintain
Eurodollar Rate Loans, such Bank shall forthwith give notice of such
circumstances to the Borrower and the other Banks and thereupon (i) the
commitment of such Bank to make Eurodollar Rate Loans or convert Loans of
another Type to Eurodollar Rate Loans shall forthwith be suspended and (ii) such
Bank's Loans then outstanding as Eurodollar Rate Loans, if any, shall be
converted automatically to Base Rate Loans on the last day of each Interest
Period applicable to such Eurodollar Rate Loans or within such earlier period as
may be required by law. The Borrower hereby agrees promptly to pay the Agent for
the account of such Bank, upon demand by such Bank, any additional amounts
necessary to compensate such Bank for any costs incurred by such Bank in making
any conversion in accordance with this [Section]5.5, including any interest or
fees payable by such Bank to lenders of funds obtained by it in order to make or
maintain its Eurodollar Rate Loans hereunder.

-26-

5.6. ADDITIONAL COSTS, ETC.If any present or future applicable law, which
expression, as used herein, includes statutes, rules and regulations thereunder
and interpretations thereof by any competent court or by any governmental or
other regulatory body or official charged with the administration or the
interpretation thereof and requests, directives, instructions and notices at any
time or from time to time hereafter made upon or otherwise issued to any Bank or
the Agent by any central bank or other fiscal, monetary or other authority
(whether or not having the force of law), shall:

(a) subject any Bank or the Agent to any tax, levy, impost, duty,
charge, fee, deduction or withholding of any nature with respect to this
Credit Agreement, the other Loan Documents, any Letters of Credit, such
Bank's Commitment or the Loans (other than taxes based upon or measured by
the income or profits of such Bank or the Agent), or

(b) materially change the basis of taxation (except for changes in
taxes on income or profits) of payments to any Bank of the principal of or
the interest on any Loans or any other amounts payable to any Bank or the
Agent under this Credit Agreement or any of the other Loan Documents, or

(c) impose or increase or render applicable (other than to the extent
specifically provided for elsewhere in this Credit Agreement) any special
deposit, reserve, assessment, liquidity, capital adequacy or other similar
requirements (whether or not having the force of law) against assets held
by, or deposits in or for the account of, or loans by, or letters of credit
issued by, or commitments of an office of any Bank, or

(d) impose on any Bank or the Agent any other conditions or
requirements with respect to this Credit Agreement, the other Loan
Documents, any Letters of Credit, the Loans, such Bank's Commitment, or any
class of loans, letters of credit or commitments of which any of the Loans
or such Bank's Commitment forms a part, and the result of any of the
foregoing is

(i) to increase the cost to any Bank of making, funding, issuing,
renewing, extending or maintaining any of the Loans or such Bank's
Commitment or any Letter of Credit, or

(ii) to reduce the amount of principal, interest, Reimbursement
Obligation or other amount payable to such Bank or the Agent hereunder
on account of such Bank's Commitment, any Letter of Credit or any of
the Loans, or

(iii) to require such Bank or the Agent to make any payment or to
forego any interest or Reimbursement Obligation or other sum payable
hereunder, the amount of which payment or foregone interest or
Reimbursement Obligation or other sum is calculated by reference to
the gross amount of any sum receivable

-27-

or deemed received by such Bank or the Agent from the Borrower
hereunder,

then, and in each such case, the Borrower will, upon demand made by such Bank or
(as the case may be) the Agent at any time and from time to time and as often as
the occasion therefor may arise, pay to such Bank or the Agent such additional
amounts as will be sufficient to compensate such Bank or the Agent for such
additional cost, reduction, payment or foregone interest or Reimbursement
Obligation or other sum.

5.7. CAPITAL ADEQUACY. If after the date hereof any Bank or the Agent
determines that (i) the adoption of or change in any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) regarding capital requirements for banks or bank holding companies or any
change in the interpretation or application thereof by a court or governmental
authority with appropriate jurisdiction, or (ii) compliance by such Bank or the
Agent or any corporation controlling such Bank or the Agent with any law,
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law) of any such entity regarding capital adequacy, has the
effect of reducing the return on such Bank's or the Agent's commitment with
respect to any Loans to a level below that which such Bank or the Agent could
have achieved but for such adoption, change or compliance (taking into
consideration such Bank's or the Agent's then existing policies with respect to
capital adequacy and assuming full utilization of such entity's capital) by any
amount deemed by such Bank or (as the case may be) the Agent to be material,
then such Bank or the Agent may notify the Borrower of such fact. To the extent
that the amount of such reduction in the return on capital is not reflected in
the Base Rate, the Borrower agrees to pay such Bank or (as the case may be) the
Agent for the amount of such reduction in the return on capital as and when such
reduction is determined upon presentation by such Bank or (as the case may be)
the Agent of a certificate in accordance with [Section]5.8 hereof. Each Bank
shall allocate such cost increases among its customers in good faith and on an
equitable basis.

5.8. CERTIFICATE. A certificate setting forth any additional amounts
payable pursuant to [Sections]5.6 or 5.7 and a brief explanation of such
amounts which are due, submitted by any Bank or the Agent to the Borrower, shall
be conclusive, absent manifest error, that such amounts are due and owing. The
Agent or any Bank which becomes aware that such amounts are due and owing shall
provide such Certificate to the Borrower within a reasonable period after
becoming so aware.

5.9. INDEMNITY. The Borrower agrees to indemnify each Bank and to hold each
Bank harmless from and against any loss, cost or expense (including loss of
anticipated profits) that such Bank may sustain or incur as a consequence of (i)
default by the Borrower in payment of the principal amount of or any interest on
any Eurodollar Rate Loans as and when due and payable, including any such loss
or expense arising from interest or fees payable by such Bank to lenders of
funds obtained by it in order to maintain its Eurodollar Rate Loans,

-28-

(ii) default by the Borrower in making a borrowing or conversion after the
Borrower has given (or is deemed to have given) a Loan Request or a Conversion
Request relating thereto in accordance with [Section]2.6 or [Section]2.7 or
(iii) the making of any payment of a Eurodollar Rate Loan or the making of any
conversion of any such Loan to a Base Rate Loan on a day that is not the last
day of the applicable Interest Period with respect thereto, including interest
or fees payable by such Bank to lenders of funds obtained by it in order to
maintain any such Loans.

5.10. INTEREST AFTER DEFAULT.

5.10.1. OVERDUE AMOUNTS. Overdue principal and (to the extent
permitted by applicable law) interest on the Loans and all other overdue
amounts payable hereunder or under any of the other Loan Documents shall
bear interest compounded monthly and payable on demand at a rate per annum
equal to two percent (2%) above the Base Rate until such amount shall be
paid in full (after as well as before judgment).

5.10.2. AMOUNTS NOT OVERDUE. During the continuance of a Default or an
Event of Default the principal of the Loans not overdue shall, until such
Default or Event of Default has been cured or remedied or such Default or
Event of Default has been waived by the Majority Banks pursuant to
[Section]26, bear interest at a rate per annum equal to the greater of (i)
two percent (2%) above the rate of interest otherwise applicable to such
Loans pursuant to [Section]2.5 and (ii) the rate of interest applicable to
overdue principal pursuant to [Section]5.10.1.

6. GUARANTIES AND PLEDGE OF SECURITIES.
-----------------------------------

The Obligations shall be guaranteed by each Guarantor pursuant to the terms
of the Guaranties; PROVIDED, HOWEVER, that until the Guaranty Delivery Date, the
Guaranty of Hadco Acquisition shall be limited to an amount equal to the Maximum
Guaranteed Loan Value. The obligations of Hadco Acquisition under its Guaranty
shall be secured by a pledge of all of the Securities owned by Hadco Acquisition
pursuant to the Stock Pledge Agreement; PROVIDED, HOWEVER, that so long as no
Default or Event of Default has occurred and is continuing, the Agent shall
release such pledge on the Guaranty Delivery Date.

7. REPRESENTATIONS AND WARRANTIES.

The Borrower represents and warrants to the Banks and the Agent as follows:

7.1. CORPORATE AUTHORITY.

Credit Agreement and the other Transaction Documents to which any of the
Transaction Parties is or is to become a party and the transactions

7.4.1. FINANCIAL STATEMENTS. There has been furnished to each of the
Banks a consolidated balance sheet of the Borrower and its Subsidiaries as
at the Balance Sheet Date, and a consolidated statement of income of the
Borrower and its Subsidiaries for the fiscal year then ended, certified by

year then ended. There are no contingent liabilities of the Borrower or any
of its Subsidiaries as of the Balance Sheet Date, or of Zycon and its

the Borrower and its Subsidiaries following the Tender Offer and the Merger

Bank, disclose all assumptions made with respect to general economic,
financial and market conditions used in formulating such projections. To

Sheet presents fairly in accordance with generally accepted accounting
principles used in connection with the preparation of historical financial
statements the financial position of the Borrower and its Subsidiaries on a
PRO FORMA basis and properly gives effect in accordance with generally
accepted accounting principles used in connection with the preparation of
historical financial statements to the application of the PRO FORMA

contemplated in the Transaction Documents. There are no liabilities or
contingent liabilities of the Borrower and its Subsidiaries which are

consolidated statements of income for the fiscal year of the Borrower or, as the
case may be, Zycon then ended, other than changes in the ordinary course of
business that have not had any materially adverse effect, either individually or
in the aggregate, on the business or financial condition of the Borrower and its

Transaction Parties, considered as a whole, or materially impair the right of
the Transaction Parties, considered as a whole, to carry on business
substantially as now conducted by them, or result in any substantial liability
not adequately covered by insurance, or for which adequate reserves are not
maintained on the consolidated balance sheet of the Borrower and its
Subsidiaries, or which question the validity of this Credit Agreement or any of

7.15. EMPLOYEE BENEFIT PLANS.

41
-34-

7.15.1. IN GENERAL. Each Employee Benefit Plan and each Guaranteed
Pension Plan has been maintained and operated in compliance in all material
respects with the provisions of ERISA and, to the extent applicable, the
Code, including but not limited to the provisions thereunder respecting
prohibited transactions and the bonding of fiduciaries and other persons
handling plan funds as required by [Section]412 of ERISA. The Borrower has
heretofore delivered to the Agent the most recently completed annual
report, Form 5500, with all required attachments, and actuarial statement
required to be submitted under [Section]103(d) of ERISA, with respect to
each Guaranteed Pension Plan.

7.15.2. TERMINABILITY OF WELFARE PLANS. No Employee Benefit Plan which
is an employee welfare benefit plan within the meaning of [Section]3(1) or
[Section]3(2)(B) of ERISA provides benefit coverage subsequent to
termination of employment except as required by Title I, Part 6 of ERISA or
applicable state insurance laws. The Borrower or, as the case may be, Zycon
may terminate each such Plan at any time (or at any time subsequent to the
expiration of any applicable bargaining agreement) in the discretion of the
Borrower or Zycon without liability to any Person other than for claims
arising prior to termination.

7.15.3. GAURANTEED PENSION PLANS. Each contribution required to be
made to a Guaranteed Pension Plan, whether required to be made to avoid the
incurrence of an accumulated funding deficiency, the notice or lien
provisions of [Section]302(f) of ERISA, or otherwise, has been timely made.
No waiver of an accumulated funding deficiency or extension of amortization
periods has been received with respect to any Guaranteed Pension Plan, and
neither the Borrower nor any ERISA Affiliate is obligated to or has posted
security in connection with an amendment of a Guaranteed Pension Plan
pursuant to [Section]307 of ERISA or [Section]401(a)(29) of the Code. No
liability to the PBGC (other than required insurance premiums, all of which
have been paid) has been incurred by the Borrower or any ERISA Affiliate
with respect to any Guaranteed Pension Plan and there has not been any
ERISA Reportable Event, or any other event or condition which presents a
material risk of termination of any Guaranteed Pension Plan by the PBGC.
Based on the latest valuation of each Guaranteed Pension Plan (which in
each case occurred within twelve months of the date of this
representation), and on the actuarial methods and assumptions employed for
that valuation, the aggregate benefit liabilities of all such Guaranteed
Pension Plans within the meaning of [Section]4001 of ERISA did not exceed
the aggregate value of the assets of all such Guaranteed Pension Plans,
disregarding for this purpose the benefit liabilities and assets of any
Guaranteed Pension Plan with assets in excess of benefit liabilities.

7.15.4. MULTIEMPLOYER PLANS. None of the Borrower, Zycon or any ERISA
Affiliate has incurred any material liability (including secondary
liability) to any Multiemployer Plan as a result of a complete or partial
withdrawal from such Multiemployer Plan under [Section]4201 of ERISA
42

-35-

or as a result of a sale of assets described in [Section]4204 of ERISA.
None of the Borrower, Zycon or any ERISA Affiliate has been notified that
any Multiemployer Plan is in reorganization or insolvent under and within
the meaning of [Section]4241 or [Section]4245 of ERISA or is at risk of
entering reorganization or becoming insolvent, or that any Multiemployer
Plan intends to terminate or has been terminated under [Section]4041A of
ERISA.

7.16. USE OF PROCEEDS. The proceeds of the Loans shall be used for purchase
of the Securities pursuant to the terms of the Tender Offer Documents, for
refinancing of existing indebtedness of the Borrower to FNBB and of Zycon to

and for and . The Borrower will obtain Letters of Credit solely for general
corporate purposes. No portion of any Loan is to be used, and no portion of any
Letter of Credit is to be obtained, for the purpose of purchasing or carrying
any Margin Stock, except in compliance with such Regulations.

whatsoever in connection with the release of Hazardous Substances;

have been no releases on, upon, from or into any real property in the

addition, any Hazardous Substances that have been generated on any of the
Real Estate have been transported offsite only by carriers having an

to have such identification numbers, treated or disposed of only by
treatment, recycling or disposal facilities maintaining valid permits as
required under applicable Environmental Laws, which transporters and
facilities have been and are, to the best of the Borrower's knowledge,
operating in compliance with such permits and applicable Environmental
Laws; and

(d) Except with respect to matters that would not have a material
adverse effect on the value of the Real Estate or the business, assets or
financial condition of the Transaction Parties, considered as a whole, none
of the Transaction Parties or any of the Real Estate is subject to any
applicable environmental law requiring the performance of Hazardous
Substances site assessments, or the removal or remediation of Hazardous

the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to such Bank. Each of the Banks agrees with
each other Bank that (i) if an amount to be set off is to be applied to
Indebtedness of the Borrower to such Bank, other than Indebtedness evidenced by
the Notes held by such Bank or constituting Reimbursement Obligations owed to
such Bank, such amount shall be applied ratably to such other Indebtedness and
to the Indebtedness evidenced by all such Notes held by such Bank or
constituting Reimbursement Obligations owed to such Bank, and (ii) if such Bank
shall receive from the Borrower, whether by voluntary payment, exercise of the
right of setoff, counterclaim, cross action, enforcement of the claim evidenced
by the Notes held by, or constituting Reimbursement Obligations owed to, such
Bank by proceedings against the Borrower at law or in equity or by proof thereof
in bankruptcy, reorganization, liquidation, receivership or similar proceedings,
or otherwise, and shall retain and apply to the payment of the Note or Notes
held by, or Reimbursement Obligations owed to, such Bank any amount in excess of
its ratable portion of the payments received by all of the Banks with respect to

-63-

the Notes held by, and Reimbursement Obligations owed to, all of the Banks, such
Bank will make such disposition and arrangements with the other Banks with
respect to such excess, either by way of distribution, PRO TANTO assignment of
claims, subrogation or otherwise as shall result in each Bank receiving in
respect of the Notes held by it or Reimbursement obligations owed it, its
proportionate payment as contemplated by this Credit Agreement; PROVIDED that if
all or any part of such excess payment is thereafter recovered from such Bank,
such disposition and arrangements shall be rescinded and the amount restored to
the extent of such recovery, but without interest.

15. THE AGENT.
---------

together with such powers as are reasonably incident thereto, PROVIDED that
no duties or responsibilities not expressly assumed herein or therein shall
be implied to have been assumed by the Agent.

(b) The relationship between the Agent and each of the Banks is that

Documents shall be construed to create an agency, trust or other fiduciary
relationship between the Agent and any of the Banks.

certain rights and perform certain duties and responsibilities hereunder
and under the other Loan Documents, the Agent is nevertheless a
"representative" of the Banks, as that term is defined in Article 1 of the
Uniform Commercial Code, for purposes of actions for the benefit of the
Banks and the Agent with respect to all collateral security and guaranties
contemplated by the Loan Documents.

15.2. EMPLOYEES AND AGENTS. The Agent may exercise its powers and execute
its duties by or through employees or agents and shall be entitled to take, and
to rely on, advice of counsel concerning all matters pertaining to its rights
and duties under this Credit Agreement and the other Loan Documents. The Agent
may utilize the services of such Persons as the Agent in its sole discretion may
reasonably determine, and all reasonable fees and expenses of any such Persons
shall be paid by the Borrower.

15.3. NO LIABILITY. Neither the Agent nor any of its shareholders,
directors, officers or employees nor any other Person assisting them in their
duties nor any agent or employee thereof, shall be liable for any waiver,
consent or approval given or any action taken, or omitted to be taken, in good
faith by it

-64-

or them hereunder or under any of the other Loan Documents, or in connection
herewith or therewith, or be responsible for the consequences of any oversight
or error of judgment whatsoever, except that the Agent or such other Person, as
the case may be, may be liable for losses due to its willful misconduct or gross
negligence.

15.4. NO REPRESENTATIONS. The Agent shall not be responsible for the
execution or validity or enforceability of this Credit Agreement, the Notes, the
Letters of Credit, any of the other Loan Documents or any instrument at any time
constituting, or intended to constitute, collateral security for the Notes, or
for the value of any such collateral security or for the validity,
enforceability or collectability of any such amounts owing with respect to the
Notes, or for any recitals or statements, warranties or representations made
herein or in any of the other Loan Documents or in any certificate or instrument
hereafter furnished to it by or on behalf of the Borrower or any of the other
Transaction Parties, or be bound to ascertain or inquire as to the performance
or observance of any of the terms, conditions, covenants or agreements herein or
in any instrument at any time constituting, or intended to constitute,
collateral security for the Notes or to inspect any of the properties, books or
records of the Borrower or any of the Transaction Parties. The Agent shall not
be bound to ascertain whether any notice, consent, waiver or request delivered
to it by the Borrower or any holder of any of the Notes shall have been duly
authorized or is true, accurate and complete. The Agent has not made nor does it
now make any representations or warranties, express or implied, nor does it
assume any liability to the Banks, with respect to the credit worthiness or
financial conditions of the Borrower or any of the Transaction Parties. Each
Bank acknowledges that it has, independently and without reliance upon the Agent
or any other Bank, and based upon such information and documents as it has
deemed appropriate, made its own credit analysis and decision to enter into this
Credit Agreement.

15.5. PAYMENTS.
--------

15.5.1. PAYMENTS TO AGENT. A payment by the Borrower to the Agent
hereunder or any of the other Loan Documents for the account of any Bank
shall constitute a payment to such Bank. The Agent agrees promptly to
distribute to each Bank such Bank's PRO RATA share of payments received by
the Agent for the account of the Banks except as otherwise expressly
provided herein or in any of the other Loan Documents.

15.5.2. DISTRIBUTION BY AGENT. If in the opinion of the Agent the
distribution of any amount received by it in such capacity hereunder, under
the Notes or under any of the other Loan Documents might involve it in
liability, it may refrain from making distribution until its right to make
distribution shall have been adjudicated by a court of competent
jurisdiction. If a court of competent jurisdiction shall adjudge that any
amount received and distributed by the Agent is to be repaid, each Person
to whom any such distribution shall have been made shall either repay to

-65-

the Agent its proportionate share of the amount so adjudged to be repaid or
shall pay over the same in such manner and to such Persons as shall be
determined by such court.

15.5.3. DELINQUENT BANKS. Notwithstanding anything to the contrary
contained in this Credit Agreement or any of the other Loan Documents, any
Bank that fails (i) to make available to the Agent its pro rata share of
any Loan or to purchase any Letter of Credit Participation or (ii) to
comply with the provisions of [Section]14 with respect to making
dispositions and arrangements with the other Banks, where such Bank's share
of any payment received, whether by setoff or otherwise, is in excess of
its PRO RATA share of such payments due and payable to all of the Banks, in
each case as, when and to the full extent required by the provisions of
this Credit Agreement, shall be deemed delinquent (a "Delinquent Bank") and
shall be deemed a Delinquent Bank until such time as such delinquency is
satisfied. A Delinquent Bank shall be deemed to have assigned any and all
payments due to it from the Borrower, whether on account of outstanding
Loans, Unpaid Reimbursement Obligations, interest, fees or otherwise, to
the remaining nondelinquent Banks for application to, and reduction of,
their respective PRO RATA shares of all outstanding Loans and Unpaid
Reimbursement Obligations. The Delinquent Bank hereby authorizes the Agent
to distribute such payments to the nondelinquent Banks in proportion to
their respective pro rata shares of all outstanding Loans and Unpaid
Reimbursement Obligations. A Delinquent Bank shall be deemed to have
satisfied in full a delinquency when and if, as a result of application of
the assigned payments to all outstanding Loans and Unpaid Reimbursement
Obligations of the nondelinquent Banks, the Banks' respective PRO RATA
shares of all outstanding Loans and Unpaid Reimbursement Obligations have
returned to those in effect immediately prior to such delinquency and
without giving effect to the nonpayment causing such delinquency.

15.6. HOLDERS OF NOTES. The Agent may deem and treat the payee of any Note
or the purchaser of any Letter of Credit Participation as the absolute owner or
purchaser thereof for all purposes hereof until it shall have been furnished in
writing with a different name by such payee or by a subsequent holder, assignee
or transferee.

15.7. INDEMNITY. The Banks ratably agree hereby to indemnify and hold
harmless the Agent from and against any and all claims, actions and suits
(whether groundless or otherwise), losses, damages, costs, expenses (including
any expenses for which the Agent has not been reimbursed by the Borrower as
required by [Section]16), and liabilities of every nature and character arising
out of or related to this Credit Agreement, the Notes, or any of the other Loan
Documents or the transactions contemplated or evidenced hereby or thereby, or
the Agent's actions taken hereunder or thereunder, except to the extent that any
of the same shall be directly caused by the Agent's willful misconduct or gross
negligence.

-66-

15.8. AGENT AS BANK. In its individual capacity, FNBB shall have the same
obligations and the same rights, powers and privileges in respect to its
Commitment and the Loans made by it, and as the holder of any of the Notes and
as the purchaser of any Letter of Credit Participations, as it would have were
it not also the Agent.

15.9. RESIGNATION. The Agent may resign at any time by giving sixty (60)
days prior written notice thereof to the Banks and the Borrower. Upon any such
resignation, the Majority Banks shall have the right to appoint a successor
Agent. Unless a Default or Event of Default shall have occurred and be
continuing, such successor Agent shall be reasonably acceptable to the Borrower.
If no successor Agent shall have been so appointed by the Majority Banks and
shall have accepted such appointment within thirty (30) days after the retiring
Agent's giving of notice of resignation, then the retiring Agent may, on behalf
of the Banks, appoint a successor Agent, which shall be a financial institution
having a rating of not less than A or its equivalent by Standard & Poor's
Corporation. Upon the appointment of and acceptance by a successor Agent and so
long as no Default or Event of Default has occurred and is continuing, the
resigning Agent will pay to the successor Agent a PRO RATA portion of the annual
Agent's fee described in the Agent's Side Letter, calculated by multiplying the
annual amount of such fee by a fraction, the numerator of which is 365 MINUS the
number of days which have elapsed since the Borrower's most recent payment of
such fee and the denominator of which is 365. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. After any retiring Agent's
resignation, the provisions of this Credit Agreement and the other Loan
Documents shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Agent.

16. EXPENSES.
--------

The Borrower agrees to pay (a) the reasonable costs of producing and
reproducing this Credit Agreement, the other Loan Documents and the other
agreements and instruments mentioned herein, (b) any taxes (including any
interest and penalties in respect thereto) payable by the Agent or any of the

administration thereof after the occurrence of a Default or Event of Default and
(ii) any litigation, proceeding or dispute whether arising hereunder or
otherwise, in any way related to any Bank's or the Agent's relationship with the
Borrower or any of the other Transaction Parties (but excluding disputes solely
between or among the Banks), or related to the Merger or the Tender Offer, and
(f) all reasonable fees, expenses and disbursements of any Bank or the Agent
incurred in connection with UCC searches. The covenants of this [Section]16
shall survive payment or satisfaction of all other Obligations.

17. INDEMNIFICATION.
---------------

The Borrower agrees to indemnify and hold harmless the Agent and the Banks
from and against any and all claims, actions and suits whether groundless or
otherwise, and from and against any and all liabilities, losses, damages and
expenses of every nature and character arising out of this Credit Agreement or
any of the other Loan Documents or the transactions contemplated hereby
including, without limitation, (a) any actual or proposed use by the Borrower or
any of the other Transaction Parties of the proceeds of any of the Loans or
Letters of Credit, (b) the Borrower or any of the other Transaction Parties

to, claims with respect to wrongful death, personal injury or damage to
property), in each case including, without limitation, the reasonable fees and
disbursements of counsel and allocated costs of internal counsel incurred in
connection with any such investigation, litigation or other proceeding;
PROVIDED, HOWEVER, that such indemnity shall not apply to the portion, if any,
of any such losses, claims, damages, liabilities or related expenses of any
Person seeking indemnification that is determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the
willful misconduct or gross negligence of such Person seeking indemnification.
In litigation, or the preparation therefor, the Banks and the Agent shall be
entitled to select their own counsel and, in addition to the foregoing
indemnity, the Borrower agrees to pay promptly the reasonable fees and expenses
of such counsel. If, and to the extent that the obligations of the Borrower
under this [Section]17 are unenforceable for any reason, the Borrower hereby
agrees to make the maximum contribution to the payment in satisfaction of such
obligations which is permissible under

-68-

applicable law. The covenants contained in this [Section]17 shall survive
payment or satisfaction in full of all other Obligations.

18. SURVIVAL OF COVENANTS, ETC.
--------------------------

All covenants, agreements, representations and warranties made herein, in
the Notes, in any of the other Transaction Documents or in any documents or
other papers delivered by or on behalf of the Borrower or any of the other
Transaction Parties pursuant hereto shall be deemed to have been relied upon by
the Banks and the Agent, notwithstanding any investigation heretofore or
hereafter made by any of them, and shall survive the making by the Banks of any
of the Loans and the issuance, extension or renewal of any Letters of Credit, as
herein contemplated, and shall continue in full force and effect so long as any
Letter of Credit or any amount due under this Credit Agreement or the Notes or
any of the other Loan Documents remains outstanding or any Bank has any
obligation to make any Loans or the Agent has any obligation to issue, extend or
renew any Letter of Credit, and for such further time as may be otherwise
expressly specified in this Credit Agreement. All statements contained in any
certificate or other paper delivered to any Bank or the Agent at any time by or

hereunder or under any of the other Loan Documents for its account, deliver to
the Borrower and the Agent certification as to its exemption from deduction or
withholding of any United States federal income taxes. Anything contained in
this [Section]19 to the contrary notwithstanding, any Bank may at any time
pledge all or any portion of its interest and rights under this Credit Agreement
(including all or any portion of its Notes) to any of the twelve Federal Reserve
Banks organized under [Section]4 of the Federal Reserve Act, 12 U.S.C.
[Section]341. No such pledge or the enforcement thereof shall release the
pledgor Bank from its obligations hereunder or under any of the other Loan
Documents.

of its rights or obligations under any of the Loan Documents without the prior
